Elimination pattern of aroclor 1254 components in the bobwhite
The gas-liquid chromatographic profile for Aroclor 1254 did not maintain its integrity in bobwhite quail fed Aroclor 1254 for 14 days and clean food 14 or 42 days thereafter. Absorption of all components occurred at essentially the same rate, as shown by analysis of quail sacrificed within an hour after a single oral dose of Aroclor. Acentonitrile-hexane partitioning altered the peak pattern of th

Eggshell thinning, chlorinated hydrocarbons, and mercury in inland aquatic bird eggs, 1969 and 1970
In the Upper Great Lakes States, 9 out of 13 species of fish-eating birds were found in 1969-70 to have sustained statistically significant decreases in eggshell thickness since 1946. Maximum changes in a thickness index occurred in great blue herons (-25%), red-breasted mergansers (-23%), common mergansers (-15%). and double-crested cormorants (-15%). Heron eggs taken in Louisiana generally dis

Propagation of barn owls in captivity
Some aspects of the biology and life history of native birds often are more readily obtained in captivity than in the field. This is particularly true in evaluating the effects of pesticides or other pollutants on birds, because establishing cause-and-effect relationships requires experimental studies. Few wild species have been bred in captivity with sufficient success to permit the large-scale s

Drought displaced movement of North American pintails into Siberia
During the years 1954-70, 230 pintails (Anas acuta) banded in North America were reported from eastern Asia, primarily Siberia. Most of the birds were shot on the breeding grounds in May. The movement into eastern Asia of pintails banded in the interior of North America was directly correlated with the overflight of the southern portion of the breeding range in North America (r = +0.73**); this
